feat(mcp): add OpenCode ingest readiness checks

Expose a check_ingest_opencode_readiness MCP tool for remote operators and run the same static preflight before launching OpenCode ingest jobs.

The preflight validates the OpenCode binary, required run flags, project AGENTS/skill context files, and can run a no-write smoke test that proves wiki-ingest loads successfully.

Document the remote ingest workflow and clarify that wiki-file-assets is tool-first, so empty resources/prompts lists are not a failure signal.

Validation: python3 -m unittest discover -v; python3 -m py_compile obsidian_wiki/mcp_ingest.py obsidian_wiki/mcp_server.py tests/test_mcp_ingest.py tests/test_mcp_server_remote.py; git diff --check; real OpenCode smoke test passed with opencode 1.17.13.

+This adds write-capable MCP tools to the same `wiki-file-assets` server and bearer token. The server is tool-first: some MCP clients may show empty `resources` or `prompts` lists until a concrete `asset://source/sha256/...` URI is returned by `get_file_asset_metadata`, so use the tool list as the source of truth.
 
 - `create_ingest_upload` — reserves a controlled runtime staging path for one uploaded file.
 - `append_ingest_upload_chunk` — appends base64 file chunks; defaults to 4MB decoded chunks.
 - `complete_ingest_upload` — verifies declared size and SHA-256.
+- `check_ingest_opencode_readiness` — verifies the local OpenCode binary, required run flags, project ingest skills, and optionally runs a no-write smoke test that confirms `wiki-ingest` can be loaded.
 - `start_ingest_job` — queues a local `opencode run --auto --format json` job with a fixed `/wiki-ingest` prompt for the completed uploads.
 - `get_ingest_job_status`, `get_ingest_job_result`, `cancel_ingest_job` — inspect or cancel the local job.
 
-Uploads land under `.runtime/mcp-ingest/uploads/`, outside the Obsidian vault, and are treated only as temporary source staging. Job state and logs live under `.runtime/mcp-ingest/jobs/`. The MCP server refuses to enable ingest if `OBSIDIAN_MCP_INGEST_RUNTIME_ROOT` points inside the vault; let `wiki-ingest` decide how to archive sources into `_sources/archive/`, update registries, and rebuild the file index. The ingest prompt is generated by the MCP service and restricts OpenCode to the uploaded file list; clients cannot pass arbitrary shell commands through this interface. Because enabling ingest gives the remote token write access to the vault through local OpenCode, keep it on a trusted network and rotate the token if it has been shared too broadly.
+Run `check_ingest_opencode_readiness` before the first remote upload. Use `run_smoke_test: true` when you want OpenCode itself to prove it can load the project `wiki-ingest` skill; otherwise the static preflight is also run automatically before every `start_ingest_job`.
